Energy Transfer from Dye–Zeolite L Antenna Crystals to Bulk Silicon

Artificial antenna systems: Zeolite L crystals loaded with a fluorescing donor dye and modified at the external surface with an acceptor dye are studied on a semiconductor surface (see picture). Radiationless excitation energy transfer from the donor dye to the acceptor dye and further through a thin insulating layer to the semiconductor is observed.
